SD6109

VOLTAGE MODE PWM POWER SUPPLY WITH BUILT-IN SUPERVISOR,

PROTECTION AND REGULATION FOR PCs

DESCRIPTION

The SD6109 is a power management IC for computers.

It integrates various monitoring functions and protections, such as

AC fail detection, over power protection, negative voltage protection,

over/under voltage protection and provides power down signal for

PG.

Built-in high precision oscillator provides accurate protection and

delay time for monitoring. And internal regulators TL431 are used for

stable output 3.3V and 5V, with few peripheral components.

Built-in soft-start decreases stress of transformer against saturation.

SD6109 used for pull-push or half-bridge power system with high

efficiency and stability.

DIP-20-300-2.54

FEATURES

APPLICATIONS

* Advanced Bi-CMOS process.

*4KV HBM ESD protection
